Application filed July 11, 1914. Serial No. 850,525.

To all whom it may concern:

Be it known that we, MAsoN B. GlennsoN, a citizen of the United States of America, and HERBERT Itonnnrs, a subject of the King of Great Britain and Ireland, the former a resident of the city of Detroit, in the G county of Wayne and State of Michigan, and the latter a resident of Walkerville, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Railway-Trucks, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to trucks for railway cars, and it is the primary object of the invention to facilitate the detachment and attachment of the wheels.

It is a further object to improve various details as hereinafter set forth.

In the drawings: Figure 1 is a side elevation of the truck; Fig. 2 is an end elevation thereof; and Fig. 3 is a plan view.

In the present state of the art it is usual to construct railway truck frames so that the wheels and axles can only be engaged therewith by a relative vertical movement. This necessitates the jacking up of the car to a sufficient height to provide the necessary clearance whenever an axle is to be removed or replaced. With our improved construction the axles may be engaged with the truck frame by a relative lateral movement and the construction is such that the parts are securely locked together during use and at the same time are capable of being quickly detached.

In detail, A is one of the side frames of the truck, preferably formed of malleable cast metal. In the center of this frame is an opening B through which the bolster C may be inserted, and above this opening are guides D for slidably engaging flanges E on the bolster.

F is a tie beam for connecting the frames A upon opposite sides of the truck and which is arranged in a seat below the aperture B and secured by rivets F.

The opposite ends of the truck frame are bifurcated at G and G to receive the detachable journal boxes I-I insertible between the furcations from the end of the frame. Each of these journal boxes is locked in position by a member I, which at its upper end is hinged to the upper furcation G, preferably by an integral pivot pin J engaging a hook K at the end of the furcation. The lower end of the member I on gages a hook L at the end of the furcation and is locked in engagement therewith by clamping bolts M. These bolts are pivotally attached to a pin N extending transversely through the member G and are capable of being swung outward into the po sition shown in dotted lines Fig. l, to provide clearance for the engagement of the member I, which is slotted at O for engagement with said bolts.

is a transversely-extending pin for passing through the upper end of the member I and beneath the hook K for preventing the lifting of said member out of engagement with the hook L. Thus accidental disengagement of the member I is prevented, first, by the clamping bolts M, and second, by the pin P, both of which hold said member in engagement with the hooks K and I1 and hold it from lateral displacement.

The box H is provided on its opposite sides with vertical grooves, which are engaged by projecting lugs Q, and Q formed respectively 011 the frame member A and the member I. This holds the box from lateral displacement, while permitting relative vertical adjustment. The frame is yieldably supported upon the box by springs It which are seated in recesses S formed in the upper portion of the furcation G. The lower end of the spring engages an abutment plate R which is connected to a central bolt or stem R passing upward and through an aperture in the top of the recess portion S, while nuts R engaging the threaded upper end of the bolt form a means of placing a tension upon the spring and limiting the downward movement of the follower R. The bolster C is supported upon springs T which are arranged in the recess B, and between the bolster and the tie plate F. These springs are arranged between abutment plates T at their opposite ends, which are connected by the central bolt T for placing the desired tension thereon and for limiting outward movement of the springs. The plates T are provided with pins or lugs U for engaging recesses in the bolster C and a bearing plug V on the cross tie F, thereby holding said spring from lateral displacement.

With the construction as described, to assemble the truck, the side frames A are connected by the tie plate F, after which the bolster C may be inserted through the apertures B and raised to engage the flanges E with the guides D, the springs '1 being then placed beneath the bolster to yieldably support the same. To engage the wheels, the boxes H are mounted upon the axles and are then engaged with the furcations G G, the member I being first disengaged and swung upward upon the hinge pivot J. When the box is in position the member I is swung downward and engaged with the hook L, after which the clamping bolts M are tightened and the pin P is inserted to hold said member from accidental disengagement. Before the box is engaged with the bifurcated end of the frame, the spring R is engagedwith the recess S and is placed under tension by the nuts R upon the central bolt R By thus tightening the nuts the follower plate B may be raised so as to provide clearance for the box H when t s laterally inserted. As soon as the box is in position and the member I looked the lugs Q and Q, engaging the vertical grooves in the sides of the box, will guide the latter, while permitting vertical oscillations of the frame through the yielding of the spring R.

When at any time it is desired to remove one or ,more of the wheels, it is only necessary to jack up the frame enough to relieve the weight from the axles and wheels. The member I may then be disengaged by first releasing the clamping bolts M and then withdrawing the pin P, which permits of lifting said member I out of engagement with the hook L and of then swinging it upward out of thepath of the box H.

What we claim as our invention is 1. A railway truck, comprising a side frame having a bifurcated end portion, an axle journal box insertible between the furcations, a member having a pivotal engagement with the upper furcation, and a hooked engagement with the lower furcation, forming a keeper for retaining the box, and locking means for normally holding said member from disengagement.

2. A railway truck, comprising a side frame having a bifurcated end portion, an axle journal box insertible between the furcations thereof, a spring for yieldably and resiliently supporting the frame on said box, means for retaining said spring in engagement with the upper furcation to permit of the insertion and withdrawal of said box, and, a member for closing the outer end of said furcations to retain said box from displacement.

3. A railway truck, comprising a side frame having a bifurcated end portion with a recess in the upper furcation thereof, an axle journal box, laterally insertible between the furcations of said frame, a spring for supporting said frame upon said journal box located in the recess in said upper furcation, an abutment plate for the lower end of said spring, and a vertically adjustable attachment between said abutment plate and said recessed furcation for tensioning the spring and for limiting its downward movement to permit of the insertion or withdrawal of said box.

4. A railway truck, comprising a side frame having a bifurcated end portion with a recess in the upper furcation thereof, a spring engaging said recess, an abutment plate for the lower end of said spring, a rod connected to said abutment plate and extending upward through said furcation, an adjustable stop on said rod for limiting the downward movement of said abutment plate, an axle box laterally insertible between said furcations and beneath said abutment plate, and a member for closing the outer ends of said furcations and for guiding the box to permit vertical oscillation of the frame.

5. A railway truck, comprising a side frame having a bifurcated end portion with a hook at the end of the upper furcation thereof, a member having a pin at its upper end for engaging the hook on said furcation and at its lower end having a shouldered engagement with the lower furcation, locking means for holding said member in engagement with said hook and shoulder, and an axle journal box insertible between said furcations when said member is disengaged and guided by said member when in locked position to permit of relative vertical oscillation.

6. A railway truck, comprising a side frame having a bifurcated end portion, the upper fureation thereof being recessed, a spring housed in said recess, an axle journal box laterally insertible between said furcations beneath said spring, a member for closing the outer ends of said furcation to retain said box from disengagement, and laterally extending lugs formed upon said member and upon said frame for slidably engaging the opposite sides of said box to permit the relative vertical oscillation thereof.

7 A railway truck, comprising a side frame having a bifurcated endportion terminating in hooks, an axle journal box insertible between said furcations, a member having a pin at its upper end engageable with the hook on the upper furcation and its lower end engageable with the hook on the lower furcation, and locking means at both ends of said member for preventing disengagement from said hooked furcations.
